When i bought my ipad4 i registered my apple id - firstname.lastname@example.org, on the ipad. Under Settings->icloud->Mail, i turned the option to ON and it automatically created the id - email@example.com. It was this id that i used for all emails in the apple mail app. Thus, the yahoo id was used for itunes purchase and icloud id ,for emails using the apple mail app. I thought i did not want people to know my apple id that i use for itunes purchase (which could be guessed from the icloud id). So, Later, i created another apple id - firstname.lastname@example.org. I deleted my icloud account on ipad and took care to save all my contacts and calendars etc on the ipad and then signed back in with this new id. As before, under Settings->icloud->Mail, when i turned the option to ON, it automatically created the id - email@example.com. I am able to use this id viz, firstname.lastname@example.org successfully for all my email work. No problem with calendars,contacts etc. Thus now, my itunes purchases happen with email@example.com while all email,contacts,calendars etc work are done with firstname.lastname@example.org. My questions are - 1.is this a good way to use different id for both? 2.Will it create any problems? 3.Does using two id's ensure any protection at all? Dear friends, please answer my questions considering that i am a novice and dumbo in idevices, though i did read up on apple id's, on the web.
